I suppose that specifically I am wondering if there are any things you do to perhaps:
- stay calm
- calm the other person down
- get them to understand you better
- understand their point of view
- diffuse trolls
- just be a good person who wants to participate in a conversation that enhances your understanding of others, different cultures, and the world and how it works
You’re not there to convince anyone. Just state your position succinctly and clearly. What the other person makes of it is up to them.
But everyone knows they’re idiots anyway so it doesn’t matter.
